I found this as well, on a Raspberry Pi 4, compiling with GCC 11.2.1_p20211127. Adding -flax-vector-conversions to the compiler flags allows this to compile, and the marbling screenhack then runs and looks plausibly like jwz's description of it. Attached is a patch to configure.ac to cause the necessary change.

You can also cast correctly.
I informed upstream via https://www.jwz.org/xscreensaver/bugs.html about this ticket. I think it should be fixed in the source, not in the flags and the patch should go upstream.
